Chungwa's Plan for Redundancy and Synchronization
With the Verimatrix revenue security solution in place, Chunghwa Telecom wanted to leverage the innovative technology to create a complete disaster recovery solution for its IPTV and over-the-top (OTT) networks.With two geo-redundant data centers in Taipei servicing customers in the northern region, and two geo-redundant data centers in Tainan servicing customers in the southern region, and high-speed networking between them, achieving multiple layers of geographic redundancy was of critical importance.To achieve this redundancy, a plan was devised to allow each regional data center to fail over to its respective backup regional data center, without any failover between the northern and southern regions. Each distinct user base would be managed independently, but with synchronization of all content ingestion occurring in the northern data centers, then being synchronized with southern data centers.To ensure Chunghwa Telecom could achieve its disaster recovery goals with its Verimatrix solution, the Verimatrix Global Services team gained an in-depth understanding of Chunghwa Telecom’s goals and then devised a comprehensive plan to address them.
